Re: detention basin

Fellow engineers,
 
        One thing that should NEVER be done is to place outdoor toilets below high water level in basins that may be used for recreational purposes.
 
        This may seem too basic to even mention but I have seen these things floating about the recreation area following heavy rain and the results are potentially dangerous as well as unpleasant.
 
Regards,

I have designed several earth detention basins- one is a soccer field which gets submerged a few times a year for a few days each time.
Another is concrete - like a box culvert and directly under a residential street- about 10'x 10' x 150 ft. long. The design is exactly like a typical box culvert.

I'm being asked to design a detention basin for a civil engineer.  the hydrology has already been done, he just needs structural detailing/design.  Having never done anything like this, i naturally have a few questions that i hope some of you may be able to answer.
 
 
1.  I tried searching for some sort of standard of design, but came up empty handed.  Do any exist?  Sources?
 
2.  I assume i'm just designing a big conrete box to hold water (19' wide x 53' long x 6.5' deep).  So Live Load would be the full volume of water, or can i consider something less?
 
3.  How about lateral loads?  How do i account for the water sloshing about?
 
4.  Should this be constructed w/ corrosive resistant materials? 
 
Any insights, thoughts, help is appreciated.
 
Thanks
